Update.......
Everything settled in and going to plan !!!
Got through the Ammonia spike and have begun to add some stock.
Some assorted Zoa's, to make a Colourful Zoa garden in on side, and a few assorted corals on the upperslope of the rockwork....got 2 acro's (yes I know, the Acro Police will say my Tank is too new, but they are doing great.
Got a Powdwr Blue AND a Purple Tang ....again my apologies to the Tang Police, but they are the best of mates !!!! and going well....keeping the rockwork squeaky clean.
I got a very small outbreak of purple Cyano on a couple of spots, but general husbandry has cleaned it up, now I see the beginnings of the inevitable brown diatoms and will deal with them next !!! These early blooms dont bug me 'cause I know that good husbandry and time, with good water parameters will ultimately take care of them, no need to pump chemicals and additives, nature will do it better and cleaner over time.
No nuisance algaes so far but I am super careful with Phosphates and Nitrates. Running GFO and GAC plus a particle filter for the time being. Water changes at about 20 % per week and a good healthy growth of Caulerpa in the sump.
Tank Parameters as of last night...
Temp 25.9
Ph 8.24
ORP 449 (not using Ozone yet...not needed with this result !)
KH 9.3
Ca 450
Mg 1290 (just upped the dose rate, target 1350)
PO4 Not detectable with Salifert Kit, waiting on delivery of Hanna Tester.
NO3 about 3 to 5 on Salifert Kit
Salinity 35
So far no billiard balls have caused problems, the guys dont want to play any more...just sit and watch the Marine display

The mechanics and dynamics of the total system continue to perform brilliantly, all is very stable and water flows are impressive. My Aragonite sand remains pristine white, thanks to the CUC and the Sand sifting Goby who works like a Trojan all day !!!
I am particularly impressed with the Bubbleking Supermarine skimmer, does not have a lot of work to do at the moment, but soon as I feed the fish and coral it fires up and cleans it all up in a flash !!!....I think it was worth the money.
I will take some photos later today and post tomorrow.
I am humbled by the request for information, I did not realise that folks were waiting for an update, I wont be so slack in the future
Cheers and thanks everybody who is following
